SAFETY-CATCH.

Specification of Letters Patent.

Patented Feb. 27, 1906.

Applieation'filed March 15, 1905. Serial No. 250,304.

To 00% whom it may concern:

Be it known that I, OTTO LAMAOOHIA, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Safety-Catches, of which the following is a specification.

This invention relates to safety devices for use in connection with brooches, class-pins, or the like of that type utilizing a spring catch-pin to secure the article to the person.

The invention comprises, essentially, a simple and practical little safety means applied to the body of the article for cooperation with the catch-pin and designed to obviate all likelihood of accidental displacement and loss of the article.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the-means for effecting the result reference is to be had to the following description and accompanying drawings.

Figure 1 is a bottom plan view of a pin embodying the invention, the interior members of the latch device being disclosed. Fig. 2is a vertical longitudinal sectional view, the catch-pin'being engaged with the latch device. Fig. 3 is a broken view of the pin, the members of the latch device being shown in positions assumed thereby when the catchpin is in engagement therewith. Fig. 4 is a plan view of the latchcasing, showing the exact formation of the spring which cooperates with the latch -plate mounted therein, the latch-plate being shown pulled out from the casing by dotted lines.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In the drawings the numeral 1 indicates the body of the pin, which may be of any of the forms of such articles, as before mentioned, and of any ornamental configuration desired. To the back of the body 1 is pivoted the catch-pin 2. The pin 2 is pivotally secured at one end to the body 1, the opposite end of the pin being deflected or curved toward the body 1, so as to'be readily passed through a slot 3 in a casing 4, containing the latch mechanism. The latch mechanism comprises mainly a latch-plate 5, slidably mounted inside of the casing 4, the outer extremity of the latch-plate being provided with an upwardly-projecting nib 6, which may be engaged by the finger in order to move the latch-plate into and out of engagement with the extremity of the catch-pin 2. The latchplate 5 is adapted to move across the slot 3, operating in the casing, of course, so that said plate will engage over the bent extremity of the pin 2 after the same has been inserted through the slot 3 of said casing, thereby effectively holding said pin 2 from disengagement. In order that the latch-plate 5 may not be accidentally moved, so as to become disengaged from the pin, said plate is cut away at a side thereof, as shown at 7, and a spring 8 is adapted to engage the cut-away portion 7 to interlock with the latch-plate after the same has been moved into engagement with the pin 2. The spring 8 consists of a body 8* and a shank 8*, having an end curved circularly, as shown at 8 The curved end of the spring will seat itself in the recess 7 of the latch-plate and frictionally binding thereagainst to effectively prevent accidental disengagement of the plate, as above premised. The nib 6 of the plate 5 may be readily moved into and out of the casing in order to disengage the pin 2 from the latch device; but this could not be done without'the knowledge of the wearer of the article for obvious reasons.

Having thus described the invention, wha is claimed as new is In a device of the class described, the combination of a body, a casing, acatch-pin, a sliding latch-plate mounted on said casing for engaging over an end of the said catch-pin, a side of the latch-plate being cut away, and a spring having an end thereof frictionally engaging a side of the plate and adapted to en ter the cut-away portion thereof at a predetermined point in its movement to prevent accidental sliding movement and disengagement of the plate from the pin.

In testimony whereof I affix my signature in presence of two witnesses.

OTTO LAMACOHIA.
